Where do you inpiut Performance Stock Unit (PSU) information. There is a selection for RSU"s, but not PSU's.

Once Performance Stock Units (PSUs) vest and the underlying stock is received by the employee, the tax treatment is exactly the same as Restricted Stock Units (RSUs).  I recommend that you do not import the Form 1099-B for any company stock sale, and instead enter it manually.  For the PSUs, just like RSUs, when the stock is issued it is a taxable event.  The value of the stock on that day is considered earned income.  It is subject to income and payroll tax withholding and is included in you box 1 of your W-2.  That amount is your total cost basis.  When you sell PSUs or RSUs, Brokers almost always report the wrong cost basis on Form 1099-B, so it has to be adjusted after entering the transaction.
